Abstract

Bali is an island that is very diverse in culture. One of the cultures that exist in Bali is a very unique means of carrying out Hindu ceremonies. The means of the ceremony itself, called Banten, is a medium for visualizing Hindu teachings and for conveying Sradha and Bhakti to Hyang Widhi's omnipotence. Now the Balinese people prefer to buy offerings for religious ceremonies. With the advent of the digitalization era, now everything can be done without meeting face to face, one of which is the field of e-commerce for buying and selling products online. Here the author is moved to create a website-based application, namely e-Banten using the waterfall method. e-Banten itself is a messaging application between Banten which is carried out via online orders. Keywords: Banten, Balinese Hindu community, Website, E-commerce, Waterfall.

Abstract

Borobudur Temple has an area of ??about 2500 square meters, with a length of 121.66 meters, a width of 121.38 meters, and a height of 35.40 meters. This colossal building is also decorated with 2,672 relief panels and 504 Buddha statues. The large number of reliefs makes people often do not know information about these reliefs. Even though each relief itself actually has many stories of its own. Due to these problems, it is necessary to have a relief detector that can help tourists to find out more information about these reliefs. In this study, the authors use template matching with the Minimum Square Difference and Normalized Cosine Coefficient methods to identify relief. The stage for relief detection starts from the preprocessing stage and then performs template matching using 2 different methods. The test results from 23 images obtained the percentage of success of the system using the Normalized Cosine Coefficient method 34,78% and Minimum Square Difference method is 82.60%.

Abstract

Nowadays, the development of IT provides many benefits for all levels of society as a solution to the problems of a job. The Faculty of Tourism of Udayana University is one of the higher education institutions that also utilizes existing IT. Data management in each study program, section or work unit used an online information system. However, in the midst of a system that is already running well, there is still a system that is carried out manually and it is very necessary to be developed in order to provide more optimal services to students, namely the Student Field Work Practice (PKL) management system. In its current management, it is still using the Ms. Word and Excel. The data is stored in several separate files so that it can result in repeated data input and takes a long time to complete the administration of student street vendors, which is only handled by one employee. Based on these problems, the authors consider it necessary to design and build a web-based Job Training Management Information System. In designing this system using the waterfall development method. The results of this study are expected to produce a design system to help settle the administration of street vendors better, so as to produce more complete, accurate and precise reports for students, lecturers and faculty leaders.

Abstract

In this Current technological developments, especially technology in the service sector, which is engaged in helping MSME communities whose system needs are becoming increasingly complex, can be seen from the widespread use and development of multi-sector information systems such as information management systems in villages or government as well as those engaged in the health sector. In 2022, most of them will start using a mobile-based system that can be accessed anywhere. With such a system, its use will be more efficient and flexible. However, to achieve an interface design that is friendly and acceptable to the user, validation is needed to determine whether the design that has been made has met the criteria required by the user. Sometimes the first design that is made does not necessarily meet the desired criteria. Therefore, we need an approach in the form of A/B testing where this is a method of comparison between design 1 and design 2, which is seen to be better in terms of usability level. This method was chosen to ensure that every existing assumption can be validated, whether or not it is true. Every time you optimize your designs, apart from being made for automation, a/b testing is usually used to help entities understand what users or the market want.

Abstract

Koperasi merupakan sebuah badan usaha yang beranggotakan sekumpulan orang yang kegiatannya berlandaskan prinsip kerjasama. Ataupun dapat disebut sebagai kegiatan ekonomi kerakyatan yang berasas kekeluargaan. Mensejahterakan nasabah atau anggota juga merupakan tujuan dari koperasi tersebut. Hampir keseluruhan sistem pelayanan ekonomi saat ini menggunakan sistem terkomputerisasi dan bahkan telah diterapkan juga pada perangkat komputer genggam atau seluler, yakni perangkat android. Begitupun dimaksudkan dalam penelitian ini untuk membangun sebuah aplikasi koperasi berbasis android sebagai pelayanan transaksi. Didalam proses transaksi pada aplikasi koperasi mobile ini menggunakan algoritma kriptografi RSA sebagai pengamanan untuk penyamaran data yang dilakukan. Data yang disamarkan dapat dipulihkan menjadi data awal hanya dengan pasangan kuncinya saja. Sedangkan untuk pengujiannya dilakukan dengan menggunakan RMSE (Root Mean Square Error) yang mendapat rata-rata hasil deskripsi 208,766377. Karna yang diuji adalah algoritma kriptografi maka semakin besar perbedaan antara data awal dan akhir, maka akan semakin baik pula karena proses dekripsinya pun akan menjadi semakin rumit

Abstract

Motorcycle is one of the needs that can be said as a necessity that must be owned by everyone, especially in the field of transportation. The use of motorbikes which are more in demand by the public is certainly not without reason given the increasingly dense means of transportation in Indonesia today. The use of a motorcycle can minimize the use of time because it is considered more effective on the trip. By choosing the right location for selling motorcycles or better known as Dealers, especially Honda Dealers in Bali, it will certainly determine the level of success, or the number of sales generated. Decision Support System (DSS) using the Analytical Hierarchy Process (AHP) method is expected to help determine priorities from various available alternative locations. The application of the Analytical Hierarchy Process (AHP) method in this study is to determine the location for the construction of a Honda Motorcycle Dealer in Bali according to the desired criteria. The Analytical Hierarchy Process (AHP) method will make it easier to make decisions. Based on the calculation of the Analytical Hierarchy Process (AHP), the priority criteria are obtained in determining the selection of development sites where the criteria are Market Share, targets and competitors. The highest ranking in the selection of Motorcycle Dealer locations in Bali, especially in Tabanan Regency, was obtained by Baturiti District with the results of the eigenvalues of 0.455.

Abstract

Bayi sangat sensitif terhadap cuaca di sekitarnya. Penyesuaian suhu ruangan sangat berpengaruh terhadap suhu tubuh bayi. Suhu ruangan yang terlalu panas dapat meningkatkan risiko SIDS pada bayi. Suhu ruangan ideal untuk bayi berkisar pada suhu 18oC sampai dengan 22oC. Untuk dapat menjaga suhu ruangan yang ideal, ketika suhu ruangan panas, maka diperlukannya penurunan suhu. Salah satu cara untuk melakukan penurunan suhu ruangan adalah dengan menyalakan kipas. Kadang kala ketika orang tua sedang sibuk pada kegiatan lain, mereka tidak sempat memperhatikan suhu ruangan bayi. Oleh karena itu, melalui paper ini, maka akan direkomendasikan suatu rangkaian yang dapat membantu para orang tua untuk dapat mengontrol suhu ruangan ideal bagi bayinya. Rangkaian yang dibangun akan menggunakan arduino, sensor suhu, serta motor dc untuk menyalakan kipas. Keywords: Kipas Otomatis, Arduino Uno, Sensor Suhu
